Transactional and Authorized Methods in your Catalyst Model Class

In a previous post I have showed how to implement a hack to have transactions and authorization around Catalyst model classes. I am now proud to say that after some uploads and a fix in MooseX::Method::Signatures (this post requires at least version 0.31 of that module), you can now write very elegant model classes.

The requirement is simple, you usually need your model methods to be enclosed in transactions and to be subject to some kind of authorization mechanism. Now the code looks like:

package MyApp::Model::MyModel;
use Moose;
use MooseX::Method::Signatures;
use aliased 'MooseX::Meta::Method::Transactional';
use aliased 'MooseX::Meta::Method::Authorized';
extends 'Catalyst::Model';
with 'Catalyst::Component::InstancePerContext';
